Earth Overshoot Day

By Earth Overshoot Day 2020, we will have used more from nature
than our planet can renew in the whole year

When will Earth Overshoot Day land in 2020?  Join our contest to guess the date!

COVID-19 UPDATE: With most schools and universities now closed around the world and students studying at home, this contest is now open to individual students and their families.

Are you a student? A teacher? Middle-school, high-school or university? Tell your class about this opportunity to learn about the Ecological Footprint, to explore data from the National Footprint Accounts, and to study the long-term trend of the global ecological deficit. We created a lesson plan to help guide you through this activity.

Your contest entry is your estimate of the date for Earth Overshoot Day 2020, together with the method you devised to get your result. The winner(s) will be featured on and Global Footprint Network’s social media!

The deadline to submit your guess is May 22, the International Day for Biological Diversity! The date of Earth Overshoot Day 2020 and the winner(s) of the Guess-the-Date Contest will be announced on June 5, World Environment Day.


Watch last year’s winners share their experience!

Thriving lives within the means of our planet are not out of reach. Plenty of solutions exist in five major areas
for improving sustainability: cities, energy, food, planet, and population.

How we design and manage cities

Eighty percent of the world population is expected to live in cities by 2050. City planning and urban development strategies are instrumental to balancing the supply of natural capital and population’s demand. Learn More



How we power ourselves

Decarbonizing the economy is our best possible chance to address climate change, and would improve the balance between our Ecological Footprint and the planet’s renewable natural resources. Learn More



How we produce, distribute, and consume food

How we meet one of our most basic needs–food–is a powerful way to influence sustainability. Sourcing food locally and avoiding highly processed foods can lower the Ecological Footprint. Learn More


How we help nature thrive

Humanity’s quality of life is dependent on the health of our planet’s biological resources including fertile soil, clean water, and clean air necessary for humanity to thrive. Learn More



How many of us there are

Being committed to everyone living secure lives in a world of finite resources requires addressing population growth. Empowering women is essential for global sustainability. Learn More

Earth Overshoot Day is an initiative of Global Footprint Network, an international research organization that is changing the way the world measures and manages its natural resources. The date of Earth Overshoot Day is calculated with data from Global Footprint Network’s National Footprint Accounts, which are now available for free on our Ecological Footprint Explorer Open Data Platform at

Wondering how you can help #MoveTheDate of Earth Overshoot Day towards one-planet living?

You’re in the right place. Since we launched the Earth Overshoot Day campaign in 2006, we’ve been calculating the date of Earth Overshoot Day each year for every year, going back to the early 1970s when the world first fell in ecological deficit. Over time, we’ve expanded this campaign to include Steps to #MoveTheDate so that anyone may feel empowered to take action in their own life. Because if we #MoveTheDate five days out every year, we’d be under one planet before 2050. More than ever we understand that #MoveTheDate can’t stop at Earth Overshoot Day and must live throughout the year. The movement keeps growing. There’s no time to lose. We need you. We depend on you. Please consider supporting our work for as little as $5. One hundred dollars helps us generate 2 million media impressions during Earth Overshoot Day. Thank you!
